refactor: rename await-kmsvc pattern to awaitTaskComplete

- Better describes the intent: awaiting task completion via queue
- More descriptive than 'await-kmsvc'
- Applied to all workflow design documents
- Reflects the actual operation: wait for external task to complete

+# Poimen CLI — Dynamic JSON-Based Design
+
+## Overview
+
+New CLI (`cmd/cli`) that accepts JSON WorkflowSpecs and dynamically understands activity sequences—same mechanism as HTTP API, but command-line interface.
+
+## Key Commands
+
+```bash
+# Submit workflow from JSON
+poimen-cli submit workflow.json
+poimen-cli submit workflow.json --wait
+poimen-cli submit workflow.json --watch
+
+# Check status
+poimen-cli status wf-abc123
+poimen-cli status wf-abc123 --wait
+
+# Template management
+poimen-cli template list
+poimen-cli template show code-review-v1
+
+# Execute immediately (sync)
+poimen-cli execute template code-review-v1 --input-file input.json
+```
+
+## Workflow JSON Example
+
+```json
+{
+  "name": "code-review-pipeline",
+  "input": {"repo": "https://github.com/..."},
+  "activities": [
+    {
+      "name": "Clone",
+      "resource": "CloneRepoActivity",
+      "parameters": {"repo": "${input.repo}"},
+      "timeout": "5m",
+      "next": "Analyze"
+    },
+    {
+      "name": "Analyze",
+      "resource": "AnalyzeCodeActivity",
+      "parameters": {"path": "${Clone.output.path}"},
+      "timeout": "10m",
+      "retry": {"maxAttempts": 3},
+      "catch": [{"errorEquals": ["Timeout"], "next": "HandleTimeout"}],
+      "next": "Judge"
+    }
+  ]
+}
+```
+
+## File Structure
+
+```
+cmd/
+  ├─ cli/                  (NEW)
+  │  ├─ main.go
+  │  └─ commands/
+  │     ├─ submit.go
+  │     ├─ status.go
+  │     ├─ template.go
+  │     ├─ execute.go
+  │     └─ history.go
+  ├─ starter/              (OLD: keep for backward compat)
+  └─ worker/
+```
+
+## Three Entry Points (Same Core)
+
+| Interface | Endpoint | Input | Output |
+|-----------|----------|-------|--------|
+| **CLI** | `submit workflow.json` | JSON file | workflow_id |
+| **CLI** | `execute template T` | Template name | Results (sync) |
+| **API** | `POST /api/v1/workflows` | JSON body | workflow_id |
+| **API** | `POST /api/v1/execute` | JSON body | Results (sync) |
+
+All use same `RoutingWorkflow` internally—just different interfaces.
